A method includes determining a location of a vehicle system traveling on a track during a first trip relative to a curve in the track. The method also includes monitoring a temperature profile at a contact interface between a wheel of the vehicle system and a rail of the track that contacts the wheel as the vehicle system traverses the curve in the track. The temperature profile is based, at least in part, on a first speed profile of the vehicle system during the first trip. The method further includes analyzing the temperature profile to detect a flanging event between the wheel and the rail as the vehicle system traverses along the curve in response to the temperature profile indicating that a flange of the wheel engages a side of the rail.

The system 100 can include: a fleet management system, a motion planner, a vehicle controller, and a track data system. The system can optionally include a user interface. However, the system 100 can additionally or alternatively include any other suitable set of components. The system functions to facilitate waypoint-based command, navigation, and/or control of rail vehicles within a rail network. Additionally or alternatively, the system can function to facilitate execution of the method S100 and/or sub-elements thereof.

A ride through control system for a machine is disclosed. The ride through control system may include a sensor associated with an asset of the machine and configured to generate a signal indicative of an operating parameter of the asset. The ride through control system may also include a user interface associated with the machine and a controller in communication with the sensor and the user interface. The controller may be configured to display on the user interface a plurality of selectable ride through control levels, each being associated with a respective operating parameter threshold, receive via the user interface a user selection of one of the plurality of ride through control levels, and automatically generate a machine control signal based on the signal generated by the sensor and the respective operating parameter threshold associated with the user selection.

A method for the contactless detection of a position of a measurement device that can be moved by a rail running gear on a track relative to at least one rail of the track. A projection of a laser beam that is projected onto the at least one rail and onto the inner side of a wheel of the rail running gear is detected by way of a camera. A detected position of the measurement device with respect to the wheel inner side is evaluated by an evaluation device. The inner side of the wheel disc is used as a reference base for determining at least one position value of the measurement device.

An abnormal situation alarming system includes a detection unit that detects an abnormal situation, an acquisition unit that acquires, when the abnormal situation is detected, information representing the circumstances of the location where the abnormal situation occurred, a calculation unit that calculates the time allowable for handling the abnormal situation from a detection result of the abnormal situation and an acquisition result of the information, and an alarming unit that gives an alarm of the detection result of the abnormal situation and a calculation result of the time.

The invention discloses a complex network-based high speed train system safety evaluation method. The method includes steps as follows: (1) constructing a network model of a physical structure of a high speed train system, and constructing a functional attribute degree of a node based on the network model; (2) extracting a functional attribute degree, a failure rate and mean time between failures of a component as an input quantity, conducting an SVM training using LIBSVM software; (3) conducting a weighted kNN-SVM judgment: an unclassifiable sample point is judged so as to obtain a safety level of the high speed train system. For a high speed train system having a complicated physical structure and operation conditions, the method can evaluate the degree of influences on system safety when a state of a component in the system changes. The experimental result shows that the algorithm has high accuracy and good practicality.
